One x keeps losing video

Hello AdamRomane1 and thank you for asking you question. The HDMI port on the TV and XBox itself can be effected by the cord not being the correct one. When replacing the cord be sure its the correct size and shape. There is also the type of HDMI cord
such as copper and gold wires. Some cords burn out on the inside and if they lose one wire that makes the cord the video signal can be interupted when trying to go through the HDMI Out port. If this did not help please feel free to msg me and I will look for
a way to fix it.

Have you tried a master reset? Hold you Xbox button on your console down, for about 15 seconds, even if it turns off, keep holding it down. Sometimes watching videos or streaming can fill your systems cache, and this is how you reset it. May or may not work,
but give it a shot!

Hello!

Thanks for reaching out to us here on the forums with this situation. I understand you're having issues with your Xbox One X being powered on but no image being displayed. Take a look and try some of the troubleshooting steps in this helpful article.Troubleshooting
a blank TV screen or monitor while your Xbox One is on. Let us know with a reply how it goes.

So troubleshooting this, I'd think about it this way.

The constant is the TV.

You say other devices worked on the cable and ports, but so did your Xbox One for a month. Did you test these other devices for a month on that port with the cable? I would use another port standard to test, and see if another device does continue to work
on the original port, but again, you're looking at comparisons, so do you have a device you use as much as the Xbox One hooked up? Those are the things I would think of to rule out what the issue is.

You've had multiple consoles, but are getting the same result, even after a period of time, but that says the issue might be with the display. If you get the same result on a different port, then I would see what options you have for support or troubleshooting
your display.

Let us know if you have any questions or more information and we can help provide some further troubleshooting, as well, if you'd like.

Yes, I hooked up my SNES mini with hdmi on my monitor and it works just fine. I normally use hdmi 1 but when it stopped working I tried hdmi 2 as well.
